I would suggest it depends on the volume of mail going through your server and your users email-habits. A lot of one-time AWL entries are spammers, but certainly not all. Seeing how AWL works, it cannot harm anyone doing an occasional cleanup. A few (recent) legitimate entries are lost, but the chance that this will lead to a false positive or false negative is small. Cleaning the database as much as once a day is a bad idea, even cleaning once a week may/will do more harm than good. With once a month, you should be in the clear, but the best way would to just keep an eye one it, and clean it when you notice there are too many one-time entries. Do something like '<check_whitelist> <auto-whitelist location> | grep "/1) --" | wc -l' to count the one time-entries. Kind Regards, Sander Holthaus
